I think it would be easier to build a box that all the gear
goes in. You then secure the box against the elements instead of the entire cabin
or boat. A couple of small fans moving moisture through the box should prevent condesation. Or build in a small dehumidifier. Either way you're not powering a 'whole boat' solution.
For my iMac, printer and stereo I have a cabinet with a plexiglass cover. When I use the computer I remove the plexiglass cover. When not in use the cover protects from splash (mostly worried about spray when removing wet foul weather
gear). However I can still see the chart plotter position through the glass. There's also space to store our two laptops. A small 12 volt fan keeps air moving through the box. Waterproof speakers are mounted outside the box so we can listen to iTunes or watch TV while secured.
Otherwise I'd second what Sean said about looking into remote
access to the servers or contracting a hosting service
. If you use them to provide a service
then having them on a boat is a bad idea period. If they are for development purposes, then I'd ask if you really need such expensive hardware
? I program ArcIMS and ArcGIS server apps and my laptop
serves as a functional server for development purposes. I couldn't host anything and it's slow, but it works for development purposes and all I have at stake is $900 laptop. Sure life is easier at the office with the real stuff, but it is nice to be able to develop anywhere I can fire up the laptop.
Also consider making do with one monitor
, keyboard and mouse to save a little space.
I've had no luck with a printer on board. Any moisture at all and the paper jams, smudges, etc. About the only thing I could think to do is keep the printer and paper in a pelican case with a couple silica gels and take out when needed.
